JUNB encodes JunB, a leucine zipper transcription factor within the AP-1 complex that integrates MAPK/ERK and JNK signaling to regulate stimulus-dependent gene expression programs. JunB modulates cell-cycle progression, differentiation, and stress and cytokine responses by partnering with FOS family proteins and binding AP-1 motifs across enhancers and promoters. Through these networks it influences immune cell activation and inflammatory signaling, and it is frequently used as a readout of immediate-early transcriptional responses. Dysregulated JUNB activity has been implicated in oncogenic transcriptional rewiring and altered immune phenotypes, supporting its study in tumor biology and inflammation-associated pathways.
JunB Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the JUNB locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within JUNB. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt JUNB function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of JUNB-disrupted clones.
